Rare occurrence of ovarian choriocarcinoma: ultrasound evaluation

Choriocarcinoma of the ovary is a rare, highly malignant tumor showing malignant trophoblastic cells and produces human chorionic gonadotropins. It can be classified as gestational and non-gestational choriocarcinoma. Non-gestational choriocarcinoma is extremely rare. Treatment is Methotrexate-based chemotherapy for the gestational type. This case study is a rare case of ovarian choriocarcinoma managed by surgical resection, followed by methotrexate-based chemotherapy, and aimed to evaluate the ultrasound characteristics of ovarian choriocarcinoma and how to arrive at the diagnosis. In cases with an elevated serum beta-human chorionic gonadotropin (beta hCG), the finding of a highly vascularized adnexal mass on ultrasound evaluation should be underlined as a clue for suspecting choriocarcinoma, particularly if the female was young with no marriage history or history of sexual intercourse and also to be highly considered in married females with history of repeated abortions, molar pregnancy or uterine choriocarcinoma.

Epidemiology of Gestational Trophoblastic Disease

Worldwide incidence rates of gestational trophoblastic disease (GTD) are difficult to estimate and compare due to large methodological differences within and between countries. Asia has generally reported higher incidence rates than Europe and North America, but modern reports have demonstrated a temporal decrease of GTD incidence rates in Asia and an increase in some European countries and North America. The main risk factors for hydatidiform mole are maternal age and previous molar events. Future studies on the epidemiology of GTD should include gestational trophoblastic neoplasia and international collaborative studies on this rare disease should be encouraged.

A case report on renal metastasis as an unusual presentation of choriocarcinoma

BACKGROUND

Choriocarcinoma is an aggressively invasive neoplasm, characterized by its rapid proliferation and propensity for metastasis to distant organs via hematogenous dissemination. Lungs (80%), vagina (30%), pelvis (20%), liver (10%), and brain (10%) are the most frequently metastasized organs. Renal metastases are very rare. The clinical manifestations of choriocarcinoma varies depending on the site of disease, making diagnosis challenging. In this report, we provide a clinical case of choriocarcinoma with metastases to the renal and pulmonary systems, displaying symptoms akin to those observed in ectopic pregnancy.

CASE PRESENTATION

A 27-year-old female, G2P1, with a previous history of full-term pregnancy in 2018, presented to the hospital with the onset of vaginal bleeding and accompanying abdominal aches. Investigations uncovered a left adnexal mass with a human chorionic gonadotropin (hCG) level of 77,4 mIU/mL and a left pulmonary nodule measuring 31 mm x 21 mm. Laparoscopy was performed due to the high suspicion of an ectopic pregnancy. However, no visible villi were identified during the surgery, and postoperative blood hCG levels continued to rise. A diagnostic curettage also failed to reveal any villi, maintaining the suspicion of a persistent ectopic pregnancy. Following two ineffective courses of methotrexate therapy, the patient was referred to our facility. Prior to her referral, an ultrasound had indicated a mass in the right kidney. However, upon arrival at our hospital, subsequent ultrasonography failed to detect any renal masses. Despite two months of outpatient monitoring, there was a sudden and significant increase in her serum hCG levels. An emergency laparoscopy was performed, revealing no pregnancy-related lesion. After surgery, the patient's hCG levels dropped dramatically to less than one-tenth of the original amount. Multisite enhanced computed tomography(CT)revealed suspicious lesions in both the renal and pulmonary regions. Upon thorough multidisciplinary consultation, a diagnosis of choriocarcinoma was entertained. Consequently, the patient successfully underwent eight cycles of chemotherapy and has remained recurrence-free for the past year.

CONCLUSIONS

This case underscores the potential for choriocarcinoma in women of reproductive age who exhibit radiological signs of renal masses. Early and accurate diagnosis, followed by prompt intervention, is essential to prevent needless surgery procedures.

Clinical features of gestational choriocarcinoma: A retrospective bicentric study

OBJECTIVE

To investigate the clinicopathological features, prognostic factors, treatment, clinical response, and outcome of gestational choriocarcinoma (GCC).

MATERIALS AND METHODS

A retrospective review was made of the clinicopathological and survival data of 13 patients who were diagnosed and treated for GCC in two referral centers in Turkey between 1992 and 2020.

RESULTS

The median age of patients was 36 years (range, 27-54 years), and seven were ≤39 years. The antecedent pregnancy was a term in nine (69.2%) cases, and the risk score was ≥7 in 11 (84.6%). According to the International Federation of Gynecology and Obstetrics 2009 staging, eight cases were in stage I, two in stage III, and three in stage IV. With the exception of one patient, all the others received combination chemotherapy (CT), and two of those were also treated with radiotherapy. Chemoresistance developed in 50% (6/12), and second-line CT was given to four of these. The overall complete response rate was 69.2%. Four patients died of chemoresistance and disease progression, all of them were with antecedent-term pregnancy, had high scores ≥7, and had metastases.

CONCLUSION

GCC is a unique subtype of gestational trophoblastic neoplasia, which differs from others in terms of poor prognosis, a frequent tendency to early metastasis, and resistance to treatment. To be able to achieve the most efficient therapy and prognosis, histopathology-based risk models should be developed.

Gestational choriocarcinoma

Gestational choriocarcinoma accounts for 5% of gestational trophoblastic neoplasms. Approximately 50%, 25%, and 25% of gestational choriocarcinoma occur after molar pregnancies, term pregnancies, and other gestational events, respectively. The FIGO scoring system categorizes patients into low (score 0 to 6) and high risk (score 7 or more) choriocarcinoma. Single-agent and multi-agent chemotherapy are used in low- and high-risk patients, respectively. Chemotherapy for localized disease has a goal of eradication of disease without surgery and is associated with favorable prognosis and fertility preservation. Most patients with gestational choriocarcinoma are cured with chemotherapy; however, some (<5.0%) will die as a result of multi-drug resistance, underscoring the need for novel approaches in this group of patients. Although there are limited data due to its rarity, the treatment response with immunotherapy is high, ranging between 50-70%. Novel combinations of immune checkpoint inhibitors with targeted therapies (including VEGFR-2 inhibitors) are under evaluation. PD-L1 inhibitors are considered a potential important opportunity for chemo-resistant patients, and to replace or de-escalate chemotherapy to avoid or minimize chemotherapy toxicity. In this review, the Rare Tumor Working Group and the European Organization for Research and Treatment of Cancer evaluated the current landscape and further perspective in the management of patients diagnosed with gestational choriocarcinoma.

Racial disparities in early pregnancy: a narrative review

PURPOSE OF REVIEW

This review introduces the recognized body of evidence on social determinants of health, which continue to show that a person's health is determined by their broader environmental and social context and that societal inequities harm health and healthcare outcomes. An area of inequity is race, which, although a social construct, has a significant impact on a person's morbidity and mortality as well as their access and experience of healthcare. Racial disparities in maternal and perinatal outcomes are widely recognized. Therefore, this review focuses on the less commonly addressed early pregnancy setting.

RECENT FINDINGS

Health inequities are present in the early pregnancy setting, as racial disparities exist in early pregnancy presentations and outcomes. Black women have a higher incidence of miscarriage, ectopic pregnancy and poorer survival rates from gestational trophoblastic neoplasms. Asian women have a statistically significantly higher incidence of gestational trophoblastic disease.

SUMMARY

The findings support the need for more consistent and detailed research on the impact of race on early pregnancy outcomes and increasing ethnic diversity among study populations for trials to ensure meaningful and applicable data. Raising awareness of this racial health inequity in early pregnancy is the first step clinicians can take to tackle this issue.

Choriocarcinoma complicated with intra-abdominal and intrapleural hemorrhage in pregnancy - case report

Background

Choriocarcinoma is a rare neoplasm, exceptionally uncommon during an ongoing pregnancy. The disease often has a metastatic character, causing severe symptoms from various anatomic sites like the lungs, central nervous system, vagina, pelvis, or liver. Due to the condition's rarity, evidence on how to treat the choriocarcinoma originating during pregnancy remains scarce.

Case presentation

Here, we present a case of a patient who developed choriocarcinoma before the 29th week of gestation. The neoplasm had a metastatic character, resulting in hemorrhage complicated by a hypovolemic shock. The patient underwent an emergency cesarean section and several surgeries to stop the massive hemorrhage. The treatment of the choriocarcinoma included chemotherapy with methotrexate followed by an EMA-CO regimen. The patient had a complete response to the therapy. The neonate suffered from complications related to prematurity.

Conclusion

Metastatic choriocarcinoma can be a diagnostic and therapeutic challenge during ongoing pregnancy. Treatment of the disease can be associated with severe complications, but a complete response to chemotherapy is possible with a favorable long-term prognosis.

Ultra-High-Risk Gestational Choriocarcinoma of the Ovary Associated with Ectopic Pregnancy

Gestational choriocarcinoma of the ovary is an exceptionally rare and highly aggressive tumor. Preoperative diagnosis of extrauterine choriocarcinoma is difficult due to nonspecific clinical presentation and its resemblance to ectopic pregnancy. Without molecular genetic analysis, it is not possible to reliably differentiate gestational from non-gestational choriocarcinoma. Here, we present a case of a 44-year-old woman who presented to our emergency department with complaints of pelvic pain, vaginal bleeding, and amenorrhea. Because of a recent history of conservatively managed ectopic pregnancy, the patient underwent emergency laparoscopy. Right-sided salpingo-oophorectomy was performed due to intraoperatively suspected ovarian ectopic pregnancy. Histopathology results revealed the diagnosis of ovarian choriocarcinoma of possible gestational origin. It was classified as FIGO stage IV and WHO ultra-high-risk, and she underwent multi-agent chemotherapy without major complications. She has remained in complete remission after a 12-month follow-up. Considering the rarity of this diagnosis, we conducted a literature review including all published cases of suspected gestational choriocarcinomas of the ovary. We conclude that due to the rarity of this entity, preoperative differentiating between ovarian ectopic pregnancy and ovarian choriocarcinoma is extremely challenging, and without molecular genetic analysis, it is not possible to identify the genetic origin of the tumor.

Choriocarcinoma of the Ovary Masquerading as Ectopic Pregnancy

Choriocarcinoma of ovary is a rare aggressive tumor of ovary. It may be gestational or nongestational tumor. High index of suspicion is required for diagnosis in reproductive age group females. Here, we present a case report of a 30-year-old female who was operated for ectopic pregnancy but was diagnosed as ovarian choriocarcinoma on histopathology. The patient had abnormally high beta-human chorionic gonadotropin levels with history of amenorrhea and negative urine pregnancy test. On laparotomy, a mass of 8 cm × 10 cm was found which was confirmed as choriocarcinoma on histopathological examination. The patient was managed with chemotherapy and responded well to treatment.

Age and racial differences in the presentation of gestational trophoblastic neoplasia

OBJECTIVE

Gestational trophoblastic neoplasia are a group of diseases with few data given their rarity. The aim of this study was to determine the age and racial differences in the presentation and survival of patients with gestational trophoblastic neoplasia in the United States.

METHODS

Data were collected from the National Cancer Database from January 2004 to December 2014. Chi-square tests, Cox regression, and Kaplan-Meier models were performed. Demographic characteristics included age at diagnosis, race, insurance status, facility location and type, community median income, high school dropout rate, education, income, and population density data.

RESULTS

There were 1004 eligible patients including 64% white (n=645), 23% black (n=233), and 8.3% Asian patients (n=83). Median age was 30.8 (range 14-59) years. Stage I, II, III, IV, and unknown were diagnosed in 32%, 5.4%, 30%, 18%, and 15% of patients, respectively, with 5-year survival of 99%, 93%, 94%, 72%, and 95%, respectively (p<0.001). Compared with national birth rates, those with gestational trophoblastic neoplasia were overrepresented at younger (age 10-19 years: 8.2% vs 4.8%) and older ages (age 40-54 years: 17% vs 3.3%). The extremes of age at presentation were more pronounced in black patients with gestational trophoblastic neoplasia (age 10-19 years: 11% vs 6.9%, 40-54 years: 18% vs 3.2%), and black patients constituted 23% of patients compared with 15% of births nationwide. Some 59% of patients were treated at Academic/Research Programs. Only 6/448 (1.3%) facilities treated more than one patient per year, and only 9% (n=92) of patients were treated at one of these high-volume facilities. On multivariable analysis, older age, higher Charlson/Deyo co-morbidity score, and higher stage disease were independently associated with worse survival (all p<0.001).

CONCLUSIONS

Gestational trophoblastic neoplasia was disproportionately higher in those at extremes of age and in black women as compared with United States national data. The lack of centralization of care justifies the need to develop regional centers of excellence for this rare malignancy.

Choriocarcinoma with lumbar muscle metastases: A case report

BACKGROUND

Choriocarcinoma is a highly malignant trophoblastic tumor that presents with early symptoms similar to those of an ectopic pregnancy. Here we present a patient with suspected ectopic pregnancy diagnosed by laparoscopic surgery in our hospital. The patient was found to have choriocarcinoma that had metastasized to the lumbar muscle and presented with symptoms similar to those of an ectopic pregnancy.

CASE SUMMARY

The patient was a 34-year-old female who complained of amenorrhea lasting 53 d, 7 d of right lower back pain, and 3 d of right lower abdominal pain. Transvaginal ultrasonography revealed the absence of a gestational sac in the uterus and a mass in the left adnexa. After 6 d of re-examination, ultrasound and computed tomography (CT) examination were performed on the mass located in the left adnexa area. We also noted that the patient’s serum β-human chorionic gonadotropin (hCG) level was increased. Considering an ectopic pregnancy, we performed a laparoscopy and hysteroscopy. During the operation, a left ovarian mixed echogenic mass approximately 2.5 cm × 2.0 cm with no villous tissue was found. Postoperative levels of serum hCG continued to increase. Lung CT examination showed lung nodules. Both CT and magnetic resonance imaging showed a mixed echogenic mass in the lumbar muscle. Considering lumbar metastasis of choriocarcinoma, six courses of cisplatin, dactinomycin, and etoposide chemotherapy were given after surgery. The patient’s serum β-hCG level decreased to normal and the mixed echogenic mass in the lumbar muscle decreased in size after the fifth course of chemotherapy. All symptoms subsequently disappeared after treatment.

CONCLUSION

In summary, lumbar metastasis from choriocarcinoma is extremely rare. Appropriate chemotherapy can successfully treat these metastasized tumors.

Epidemiology of neurologic disease in pregnancy

Many neurologic diseases in women are influenced by the physiologic and hormonal changes of pregnancy, and pregnancy itself poses challenges in both treatment and evaluation of these conditions. Some diseases, such as epilepsy and multiple sclerosis, have a high enough prevalence in the young female population to support robust epidemiologic data while many other neurologic diseases, such as specific myopathies and muscular dystrophies, have a low prevalence, with data limited to case reports and small case series. This chapter features epidemiologic information regarding a breadth of neurologic conditions, including stroke, epilepsy, demyelinating disease, peripheral neuropathies, migraine, sleep-disordered breathing, and meningioma, in women in the preconception, pregnancy, and postpartum stages.

Incidence and prognosis factors of extragonadal choriocarcinoma in males: a population-based study

Background

Choriocarcinoma usually occurs in females and sometimes occurs in the testicles of males. Extragonadal choriocarcinoma in males was previously described in case reports, and our understanding of this type of cancer has remained limited. The purpose of this study was to explore the incidence, treatment and prognostic factors of extragonadal choriocarcinoma in males.

Materials and methods

Two cohorts were identified from the Surveillance, Epidemiology, and End Results (SEER) Program by histology, tumor site and sex. One cohort of 115 patients was created using the SEER nine registries (1973–2014) to estimate the incidence. The other cohort of 197 patients was created using the SEER 18 registries (1973–2013) to estimate the patient demographics and survival.

Results

The median age at diagnosis was 30 years. The most common primary tumor location was the mediastinum followed by the retroperitoneum and the brain. Approximately 23% of patients underwent beam radiation therapy, whereas 63.5% underwent surgery. The estimated one- and 5-year cause-specific survival rates were 49% and 35%, respectively. The multivariate analysis showed that the age at diagnosis, ie, a younger age of 0–19 years old, and the primary tumor site, ie, the brain, were the independent prognostic factors and were correlated with a favorable prognosis. The median survival time of patients was 186 months, 13 months and 4 months in the 0–19, 20–49 and 50+ years of age, respectively.

Conclusion

Extragonadal choriocarcinoma in males is a rare malignancy with a poor prognosis. A young age at diagnosis and primary tumor site in the brain were the independent prognostic factors.
